Introduction Description The effect of a fault on a power system is dependent on the speed with which the fault can be detected & isolated. Modern protection schemes incorporate ever increasing functionality through the application of digital techniques to protection relay technology. The requirement for highly reliable tripping & control relay elements does however remain & often constitutes a significant cost & space requirement for protection panel designs. The system fulfils this need by providing a compact, flexible & cost effective solution. The range was developed to provide design engineers with a modular system of auxiliary relays to meet specific system configurations. The versions described in this publication have pre-defined functional & contact configurations to offer the following advantages: Simpler to specify & order; Lower cost due to model rationalization; Direct cross reference to other manufacturers models; Standardized wiring details.

Common Attributes Contact Bounce and Self Cleaning Contact bounce occurs due to the speed at which the contacts meet. If too much coil power is used then the contacts will come together with too much force causing excessive bounce. It is therefore important to only fit relay coils with adequate power to provide the force required to switch the relay at the minimum operate voltage 6% of nominal. In addition contact bounce can be greatly reduced through the addition of anti-bounce buffers. These components are added to each contact to provide a damping wiping motion when the contacts meet thus dissipating the force which would otherwise produce bounce. Contacts are constructed from silver / copper alloy, shaped & positioned to ensure very reliable, low resistance operation. Over travel of the contacts during each operation causes a wiping action ensuring a clean make. The design of the contact surface is spherical such that when the contacts are driven to an over travel position they actually wipe. This wiping motion is part of the damping action mentioned above but also provides a wiping action which serves to clean the contact area. relays are All or Nothing devices & continuous application of AC or DC voltages below the pick up level is not recommended. AC Voltages Standard 2HSM relays are not intended for operation with AC voltages. Application of continuous AC voltage below the pick up level will cause excessive power dissipation in the capacitor discharge resistor & likely result in thermal damage to the device.

Common Attributes Flag Indicators Each relay element is supplied with an operation (target) indicator. The indicator consists of a high visibility solid day glow orange mechanical flag which drops on energisation. Electrical Reset Mechanism Relay Wiring Diagrams All relays have a label attached to the internal side plate depicting the wiring information. As this stays with the product (unlike the paper wiring diagram also supplied), it cannot be lost. Operate voltage: Reset cut off: As per specified operate voltage. Instantaneous with main relay reset. Continuous application of both the high speed pick up coil & the reset coil will defeat the cut throat contact & result in overheating & thermal damage to both coils & associated circuit.
